This invention relates to" an improved power coupling device. 1 7

It is an ob'ect ot tl 's invention toprovide a safe and readily adjustable means of connecting the main driving mechanism with the pumping means for individual oil wells. The invention will be fully understood from the following description taken in con-.

nection with the'accompanying drawing in which latter- 7 l 1 is a perspective view of the coupling device with parts broken away; r Fig. 2 is a perspective view of a sleeve constituting one of theelements oil the coupling; Fig. 3 is a perspective view of a tongue which is adapted to be adjustably disposed in the sleeve; and a perspective view of a. coupling pin.

Referring particularly to the drawing, the device comprises alixed guideway in which the coupling proper is adapted to reciprocate. The fixed guide-way includes cylindrical supports 1 and 2 which are fixed rigidly in abutments 3 of concrete or the like. The cylindrical supports 1 and 2 are provided with slots 1,5 and 6 which are adapted to receive a housing 7. The housing 7 is recessed longitudinally to receive the coupling assembly for longitudinal reciprocating movement.

A groove 8 is provided in the housing for a purpose to'be later described. The portion 9 of support 1 oppositeslot 4 constitutes an abutment against which one end of the housing 7 is adapted to be positioned. The abutment is provided with a horizontally disposed slot 11 for a purpose to be later described. p

A coupling assembly is freely disposed in the guideway for longitudinal reciprocating movement. One portion of the coupling assembly includes a sleeve formed of spaced plates 13 and 141 and side bars 15. The'sleeve.

is provided with an opening 16 at one end and at its opposite end it is attached to a spacer bar 17. Spacer bar 17 is removably inserted into the slotted end or a rod line 18 which is adapted to be connected to a suitable source of power, not shown, by means of which it is driven in reciprocatory moveestthe abutment at the time when the sleeve menti A pin detachably connects rod line I 18 to spacer bar 17.v I

The couplingv assembly includes also a tongue 22 which is adapted to be inserted through opening 11 in support land'jthrough opening 16 in the/sleeve. Tongue' 22 is adapted to be connected to a suitable member to be actuated, such as a rod line,'not shown, running to a well andwhichactuates a pump in the well.

- Inuse, as for. examplein pumpingan oil well, the device 15 assembled by inserting tongue 22through the slot 11 in support'l. and mamtannng it 111 position by means of a pin 23 which extends through one' of suitale openings 24 spaced:longiaidinally of the tongue. Pin 23 is provided with a sup porting shoulder 25 which is adapted to rest upon the tongue 22 and functlon as a bearing v to engage the abutment 9 of support 1, and

is provided with a shank 26 which is adapted to extend through openings 24 of tongue 22 and into the groove 8 previously mentioned. The tongue 22 is therefore held in position against the pull of the rod line which leads to the Well. i V v ,The sleeve is then driven in longitudinal reciprocating movement in the guideway by eccentric operation of the power, and connection is made between the sleeve and tongue to lengthen 0r shorten the rod line which runs to the well. For accomplishing this result a slot 26 is' provided in the sleeve of suli'icient length to over-lapa plurality of the openings 1 2sand a pin 27 is adapted to be inserted into the slot26' and a suitable'opening 24:. Proferably the pin 27 is inserted through slot 26 into a hole 24 which is nearest support lat the portion of the stroke of the sleeve when the sleeve is nearest support 1. During travel of the sleeve away from support 1 the tongue 22 is drawn farther into the guideway. Durmg this stroke the p111 23 is removed and is reinserted into the openmg 2 1 which is hearis farthest from support land between the abutment 9 and the sleeve, whereby the tongue is held in its advanced position. The pin 27 can be withdrawn when the sleeve is farthest fromsu'pport 1 and reinserted into slot 26 and larger transversely also of the tongue than an opening 24 nearersupport 1 upon reciprocation of the sleeve back to its first mentioned position. This operation can be repeated until the rod line which runs to the well has been shortened the desired amount. The operation can be reversed to lengthen the rod line. Adjustment of the rod line is desirable also after breakage and repair of the red line in order to pull up any slack in the rod line. The holes 24; in tongue 22 extend ovally longitudinally of the tongue and are slightly the pin 23, whereby insertion of the pin' is facilitated. The slot 26 is of such a length longitudinally of the sleeve as to permit the operative to have ample time to insert pin 27 I 'in the desired opening 2 1. After. the adjustment has been made the coupling assembly reciprocat-es in the guideway and functions to transmit power.

Various changes may be made within the scope of the appended claims in which it is desiredto claim all novelty inherent in the invention as broadly as the prior art permits.

I claim: v Lhleans for transmitting reciprocating movement to a well pump, comprising a fixed guideway, a coupling assembly reciprocably disposed in the gu-ideway, the assembly including a sleeve adapted to be connected to a source of power, a tongue a portion of i which projects into the sleeve and is adjust able longitudinally of the sleeve, the tongue having a plurality of longitudinally spaced openings, the sleeve having a slot aligned with the openings and elongated to overlap a plurality of the openings, and a pin dethe sleeve having a slot aligned With the openings and elongated to overlap a plurality of the openings, and a pin detacha'bly engaging one of the openings and a portion only of the slot, the tongue having'openings in the portion exteriorly of the sleeve, a fixed abutment adjoining the last mentioned portion, and detacl-iab'le means adapted to e11- one 01" the openings and the side of the abutment facing the sleeve.
